Abstract

The invention discloses a conveyor belt or belting which comprises a solid woven carcass impregnated and coated with rubber. The warp yarns (12, 13) are comprised of polyester filamentary yarns doubled with texturised polyester yarns. Where the solid woven carcass is woven as a four ply or more construction the inner warp yarns (13) travel along a straighter path than the two outermost warp yarns (12) such that the outermost warp yarns (12) create 'pockets' at the surface of the carcass.

Description

Rubberline belting
The present invention relates to fabric and strengthen belting, particularly crash-resistant fabric belting, wherein strengthening the fabric belt carcass is made by the thicker integral fabric layer of mono-, be different from the multiple-structure belting, multiple-structure is to make with the thin fabric of multilayer, covers polyvinylchloride (PVC) or rubber on the fabric.
Processing intensive fabric belting has a large amount of technological problemses, particularly injects polyvinylchloride in the heavy weave belt carcass satisfactorily.However, intensive fabric construction usually is optimum, because fabric substrate becomes single-piece by polyvinylchloride (PVC) filler, thereby avoided the tectal problem that comes off of polyvinylchloride, this is the reason that early failure often takes place in the multilayer belting.Intensive fabric construction has improved support and resistance to cleavage equally.
Up to the present, intensive fabric construction is confined to use polyvinylchloride (PVC) as dipping agent.Yet, use the rubber exterior overplate to be good under certain conditions, for example, plunge domatic on, as everyone knows, for the outer cover that provides a kind of rubber carrying surface to adopt poly-butadiene-acrylonitrile copolymer (nitrile rubber), it and polyvinylchloride (PVC) are compatible, can merge under pressure on polyvinylchloride (PVC) surface of intensive fabric belt carcass.This technological process, relatively more expensive although can produce a kind of product of satisfaction, in some cases, be infeasible economically.
Target of the present invention provides a kind of intensive fabric belting, and the outside has rubber covering layer.And cost is not high when initial processing polyvinylchloride (PVC)/fabric substrate.
Attempt to produce the intensive fabric belting of a kind of full rubber in the past and do not succeed, reason is to be difficult to latices is injected in the heavy weave belt carcass, and, adopt the chemical bonding system not to be proved to be practicable technically.It normally is used to the tissue layer that approaches, and this kind tissue layer adopts when processing multilayer belting.When adopting chemical bonding system and intensive fabric belt carcass, the dipping agent poly-mer is difficult to fill with the space of fabric, and this will assemble the mechanical characteristics of low fabric belt carcass.
The problems referred to above now achieve a solution in the structure of strengthening the fabric belting.It is to rely on the intensive fabric belt carcass of first aspect present invention to solve.It provides a kind of intensive fabric belt carcass, injects rubber at the belt strap in-core, surface coverage rubber, and its middle longitude is made by bifilar poly-ester fibres line.This polyester line is a leavening structure, realizes with air control expansion by being called the curling technological process of blast injection.
This combination of line can provide best stretching balance.The mechanical adhesion power of single and coiled structure line and rubber has realized this stretching balance.
The poly-ester fibres line is made by the fiber of continuous elongation, and it is formed by fiber combinations parallel or that do not have to twine.The crimping polyester line is made by poly-ester fibres, and further is processed into and has appearance and the characteristic that is similar to the staple fibers line, and about this respect, the poly-ester fibres line is carried by nozzle, and it is subjected to high pressure air flow in nozzle.Line projects on the impacting body after leaving nozzle.In this process, make the single-stranded fiber that constitutes line form loop wire.They are being projected mutually combining of airstream eddy current on the impacting body with influencing the lower part by nozzle.During part loop wire is still online, thereby increase volume.And some loop wire that stretches out outside face makes line produce coiled structure.
Relatively the type testing result of poly-ester fibres line and coiled structure polyester line is as follows:
Non-crimping structure coiled structure
Breaking strength gms/denier (Denier) 8.3 4.2
Break stretch ratio 10.94% 12.02%
Preferably be woven into the fabric belt carcass of simple two-layer or three-decker, wherein all warp has same circuit, adopts this structure, and the intensity of one meter wide belt conveyor can reach 1250KNs, produces more high-intensity belting, needs to increase the quantity of warp.But, because the Density conference influences the centre portion that dipping agent is injected into belt conveyor.
Rely on a second aspect of the present invention to address this problem.It is by changing fabric construction, set up on the surface of fabric belt carcass in one " hole ", it can be provided convenience for the centre portion of dipping agent injection belting, by adopting a kind of weaving manner to solve, it is along the straight line coiled that wherein inner warp is compared with two layer lines of outermost to this problem.Inner warp preferably interweaves with each the 4th parallel.
Because the circuit of inner warp and outside warp is different, need carry out balance to their tensile properties.Otherwise, because outside warp knitting circuit is shorter, will be subjected to out-of-proportion pulling force, before inner warp was subjected to all stretching, outside warp will be broken.
In most preferred embodiment of the present invention, because the internal layer warp has adopted polyester, outer warp has adopted polyamide, as nylon 6, both tensile properties have obtained balance, and the stretch ratio of breaking of polyester is 14%, and nylon 6 is 19.5%, the difference (being typically 6%) of breaking stretch ratio 5.5% has compensated the difference of inner warp circuit, thereby has made full use of the pulling force potential of inside and outside warp.
Inner warp is preferably made bifilar with the crimping polyester line, and outside warp is made bifilar with the crimping polyester line selectively.
Concrete device reference diagram casehistory of the present invention is as follows:
Fig. 1 is the scheme drawing of the intensive fabric belt carcass of simple and easy double-decker.Warp is combined according to a first aspect of the invention by poly-ester fibres line and polyester crimped thread.
Fig. 2 is the sketch of texturized polyester wire processing device.
Fig. 3 is the scheme drawing of 4 layers of intensive fabric belt carcass of structure drawing according to a second aspect of the invention.
The intensive fabric belt carcass of two-layer (thigh) structure that is used to make belt conveyor or belting has been shown among Fig. 1.Warp 10 is combined by poly-ester fibres line and crimping polyester line.
In the use during processing belt conveyor or belting, intensive fabric belt carcass immersed in the latices in the past sending into press, and prefabricated uncured sheet rubber is attached on each surface of fabric belt carcass in press, is cured under the condition of heating and pressurization.Sheet rubber can be natural, also can be artificial.
The crimping polyester line can guarantee the mechanical adhesion power of sheet rubber on the fabric belt carcass.
Fig. 2 shows the sketch of texturized polyester wire processing device, processing unit (plant) is formed by soaking mechanism 1, curling nozzle 2 and impacting body 3, line to be curled is admitted to nozzle 2 by soaking mechanism 1, is subjected to the impact of the pressurized air stream that nozzle 2 side openings 4 come in therein.After leaving nozzle, project on the impacting body 3, in the fiber dispersion of this process center line, pack forms loop wire.
Fig. 3 is the intensive fabric belt carcass of 4 layers of structure, and the outside face of fabric belt carcass has " hole ".Be convenient to the middle part that liquid rubber flows into belt conveyor, be numbered 12 line and have short braiding circuit, made by polyamide fibre, be numbered 13 line and made by poly-ester fibres, line 12 can be in the same place with the crimping polyester wire-wound selectively with 13.
